Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption.
Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple ...
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted ...
Holographic display technology provides an ultimate solution for real 3D display and has great potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D display mainly depend ...
Many associate tequila with lime wedges, salt and parties. But the popular drink also has a negative impact on biodiversity, both on the blue agave from which it is made and, perhaps more unexpectedly, on bats. Both are threatened ...
Light, as an electromagnetic field, has two essential components: amplitude and phase. However, optical detectors, usually relying on photon-to-electron conversion (such as charge-coupled device sensors and the human eye), ...
A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...
Attempts to turn string theory into a workable theory of nature have led to the potential conclusion that our universe is a hologram—that what we perceive as three spatial dimensions is actually composed of only two. The ...
As weird as it might sound, black holes appear to be holograms.
Technology to control and harness light has existed for centuries, often as static solutions that must be custom-designed. It is only in the past couple of decades that the digital era of micro-electronics and computing has ...
